[0040] Embodiment 1

[0041] See also Figures 1 to 4 As shown, a sealing assembly provided by the present application is arranged in a cab, and a hydraulic pipeline on an armrest box 101 of the cab passes through a through hole 103 on a bottom plate 102 of the cab and is connected to a hydraulic module;

[0042] The sealing assembly includes a sealing member 105, a connecting portion 106 of the sealing member 105 is connected to the armrest box 101, and a sealing portion 107 of the sealing member 105 is connected to the bottom plate 102 and communicates with the through hole 103;

[0043] The sealing member 105 has an installation space, and the hydraulic pipeline can pass through the installation space and the through hole 103 and be connected to the hydraulic module.

[0044] Specifically, the present application is provided with a seal 105. When the hydraulic pipeline extends from the armrest box 101 and is connected to the hydraulic module through the through hole 103 on the bottom plate 102, since the through hole 103 is opened on the bottom plate 102, external dust will enter the cab through the through hole 103, thereby causing poor sealing of the cab. The present application is provided with a seal 105, and the sealing portion 107 of the seal 105 is connected to the bottom plate 102 and is connected to the through hole 103, that is, the seal 105 does not affect the hydraulic pipeline passing through the bottom plate 102, and the sealing portion 107 can seal the through hole 103 on the bottom plate 102, preventing external dust from entering the cab through the through hole 103, thereby improving the sealing of the cab.

[0045] More specifically, in the present application, the through hole 103 is sealed with a seal 105 , which not only prevents dust from entering the cab, but also improves the sealing of the cab, reduces the noise in the cab, and improves the reliability and comfort of the cab.

[0046] In this embodiment, preferably, the seal 105 has a cylindrical structure; the seal 105 with a cylindrical structure is preferably a plastic threaded tube. On the one hand, the length of the plastic threaded tube is adjustable, which is more convenient for accommodating hydraulic pipelines; on the other hand, the plastic threaded tube is lighter in weight, which reduces the weight of the seal 105 on the cab.

[0047] In this embodiment, the sealing assembly further includes a wire divider 108, which is disposed in the sealing portion 107; one end of the wire divider 108 extends toward the through hole 103 and passes through the through hole 103; the wire divider 108 is used to fix the hydraulic pipeline.

[0048] In actual use, since the cab will move left and right according to the needs of working conditions, in order to improve the stability of the hydraulic pipeline, the hydraulic pipeline is fixed by using the splitter 108.

[0049] In actual use, there are multiple hydraulic pipelines. In order to ensure that each hydraulic pipeline can be fixed, the distributor 108 is provided with multiple pipe through holes 109 at intervals, and the pipe through holes 109 correspond to the hydraulic pipelines one by one.

[0050] In this embodiment, the sealing assembly also includes a protective sleeve 110, one end of which is sleeved on the outside of a portion of the divider 108. Specifically, one end of the protective sleeve 110 is sleeved on the portion of the divider 108 except for the portion located in the through hole 103, and the protective sleeve 110 is used to improve the stability of the divider 108.

[0051] More specifically, the other end of the protective sleeve 110 extends toward the connecting portion 106 to form an extension portion 111, and the extension portion 111 is in contact with the side wall of the sealing member 105, which makes the sealing assembly structure more compact on the one hand and further improves the sealing performance of the sealing assembly on the other hand.

[0052] In this embodiment, in order to further improve the stability of the seal 105 , the sealing assembly of the present application also includes a fixing member 112 , which is disposed on the seal 105 and can pass through the base plate 102 to fix the seal 105 on the base plate 102 .

[0053] Preferably, the fixing member 112 is a fixing bolt, that is, the sealing member 105 is fixed to the floor by using the fixing bolt to prevent the sealing member 105 from moving.

[0054] In this embodiment, in order to further improve the sealing performance of the sealing assembly, a first sealing gasket is provided between the protective sleeve 110 and the sealing portion 107 .

[0055] Preferably, the first sealing gasket is made of rubber material, and specifically can be a rubber sealing ring.

[0056] In this embodiment, a second sealing gasket is provided between the protective sleeve 110 and the divider 108 .

[0057] Preferably, the second sealing gasket is made of rubber.

[0061] An armrest box 101 is provided on the bottom plate 102 of the cab body, and a through hole 103 is opened on the bottom plate 102;

[0062] The hydraulic module is disposed below the bottom plate 102, and the armrest box 101 is connected to the hydraulic module via a hydraulic pipeline;
